Root treatment with SiO2 NPs promote root development of rice and induce resistance to drought. A Root development in soil. Rice seedlings cultured in soil condition and treated with SiO2 NPs in different application methods. The length, fresh weigh and dry weight of the roots were tested 7 days after treatment. B Root development in hydroponic condition. The length, fresh weigh and dry weight of the roots were tested 7 days after treatment. C Images showing the phenotypes of the water treated control (CK) and the plant with root treatment of SiO2 NPs under drought stress for 20 days. D Water loss rates of detached leaves from (C). E The water content for different soil layers (the ordinate on the left and the abscissa below) and root length (the ordinate on the right and the abscissa above) from (C). Error bars represent SD. ** stands for significant difference P < 0. 01, * stands for significant difference P < 0.05
